您可以将TMOUT
变量设置为以秒为单位的数字,如果没有运行命令,bash希望它在自动注销外壳之前等待。
我知道这个问题与Bash&Ksh有关。但是我想我会为csh / tcsh发布类似的记录。
在FreeBSD上,默认的shell是tcsh。您可以使用autologout
tcsh shell 的功能自动注销会话。
闲置活动一分钟后,以下将自动注销会话。
freebsd82# set -r autologout=’1′
(Wait one minute)
freebsd82# auto-logout
Connection to freebsd82 closed.
在tcsh的(1)手册页描述它是这样的:
autologout (+) The first word is the number of minutes of inactivity before automatic logout. The optional second word is the number of minutes of inactivity before automatic locking. When the shell automatically logs out, it prints `auto-logout', sets the vari- able logout to `automatic' and exits. When the shell automati- cally locks, the user is required to enter his password to con- tinue working. Five incorrect attempts result in automatic logout. Set to `60' (automatic logout after 60 minutes, and no locking) by default in login and superuser shells, but not if the shell thinks it is running under a window system (i.e., the DISPLAY environment variable is set), the tty is a pseudo-tty (pty) or the shell was not so compiled (see the version shell variable). See also the afsuser and logout shell variables.
